Hi,
Thank you for visiting Microsoft Answers forum.
To resolve this issue, use the System File Checker tool (SFC.exe) to determine which file is causing the issue, and then replace the file. To do this, follow these steps:
- Open an elevated command prompt. To do this, click Start, click
All Programs, click Accessories, right-click
Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click
Allow.
- Type the following command, and then press ENTER:
sfc /scannow
The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.
Also try the clean boot to check for 3party software problems.
To help troubleshoot error messages and other issues, you can start Windows Vista by using a minimal set of drivers and startup
programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts. This article describes how to troubleshoot problems in Windows Vista by performing a clean boot. This article also describes how to start the Windows
Installer service and how to reset the computer so that it starts as usual.
Note When you perform a clean boot, you may temporarily lose some functionality. When you start
the computer as usual, the functionality returns. However, you may receive the original error message, or you may experience the original behavior.

If you are prompted for an administrator password or for confirmation, type your password, or click
Continue.
c.
On the
Generaltab, click

Load startup itemscheck box. (The
Use Original Boot.inicheck box is unavailable.)
d.
On the
Servicestab, click to select the
Hide all Microsoft servicescheck box, and then click
Disable all.
Note Following this step lets Microsoft services continue to run. These services include Networking,
Plug and Play, Event Logging, Error Reporting, and other services. If you disable these services, you may permanently delete all restore points. Do not do this if you want to use the System Restore utility together with existing restore points.
e.
Click
OK, and then click
Restart.
Step 2: Enable half of the services ****
a.
Follow steps 1a and 1b to start the System Configuration utility.
b.
Click the
Servicestab, and then click to select the
Hide all Microsoft servicescheck box.
c.
Click to select half of the check boxes in the
Servicelist.
d.
Click
OK, and then click
Restart.
Step 3: Determine whether the problem returns ****
If the problem still occurs, repeat step 1 and step 2. In step 2, click to clear half of the check boxes that you originally selected in the
Servicelist.
If the problem does not occur, repeat step 1 and step 2. In step 2, select only half of the remaining check boxes that are cleared in the
Servicelist. Repeat these steps until you have selected all the check boxes.
If only one service is selected in the Servicelist, and you still experience the problem, the selected service causes the problem. Go to step 6. If no service causes this problem, go to step 4.
Step 4: Enable half of the Startup items
a.
Perform a clean boot by repeating step 1.
b.
Click the
Startuptab, and then click to select half of the check boxes in the
Startup Itemlist.
c.
Click
OK, and then click
Restart.
Step 5: Determine whether the problem returns ****
If the problem still occurs, repeat step 1 and step 4. In step 4, click to clear half of the check boxes that you originally selected in the
Startup Itemlist.
If the problem does not occur, repeat step 1 and step 4. In step 4, select only half of the remaining check boxes that are cleared in the
Startup Itemlist. Repeat these steps until you have selected all the check boxes.
If only one startup item is selected in the Startup Itemlist, and you still experience the problem, the startup item that is selected in the list is the service that is causing the problem. Go to step 6.
If no startup item causes this problem, a Microsoft service most likely causes the problem. To determine which Microsoft service may be causing the problem, repeat step 1 and step 2 without selecting the
Hide all Microsoft servicescheck box in either step.
Step 6: Resolve the problem
After you determine the startup item or the service that causes the problem, contact the program manufacturer to determine whether the problem can be resolved. Or, run the System Configuration
Utility, and then click to clear the check box for the problem item.
Step 7: Reset the computer to start as usual ****
After you have finished troubleshooting, follow these steps to reset the computer to start as usual:
